Method and system for voltage controlled oscillator impedance control to optimize performance, efficiency, and power consumption |
摘要 |
Methods and systems for VCO impedance control to optimize performance, efficiency, and power consumption are disclosed and may include selectively coupling one of a plurality of taps on a multi-tap inductive load to a voltage controlled oscillator (VCO) on a chip comprising a plurality of transmitters and receivers. The multi-tap inductive load may comprise a multi-tap transformer or transmission line, which may be integrated on the chip, or may be integrated on a package to which the chip is coupled. A voltage swing at an output of the VCO and/or a current in the VCO may be adjusted by configuring a load of the VCO utilizing the multi-tap inductive load. The multi-tap inductive load may be coupled to the VCO utilizing one or more CMOS switches. |
